In the mind blowing stats, the supermarket chain revealed it threw away 30,000 tonnes of food in the first six months of this year alone.

The salad bags were one of the biggest culprits ending up in the bin, but of the 68% of bags of lettuce thrown away, 35% were binned by customers themselves. Probably because they got home, opened the bags and realised that in the short journey the entire contents had turned to pulp.

So is it time we turned back to good old fashion iceberg?

Here's some reasons to give a head of lettuce another chance:

1. Bagged lettuce isn't as healthy

Health experts warn that bagged salads are not as good for us as they sit in the bags longer and many of the health benefits and antioxidants of the leaves are lost in packaging.

When salad is bagged in a technique called modified atmosphere packaging, scientists have found levels of vitamins, particularly vitamin C are depleted.

2. It creates water waste

Not only does a lot of bagged salad end up in the bin, but it is more costly on the environment to produce in the first place. Ever since the bagged Spinach E.coli scare in 2006 (where 205 became sick and 3 died in America) – many companies triple wash their bagged salad, resulting in a mass of water waste.
